The approach of a star to our solar system.




For a star to approach the area of ​​the planets or the solar system is rare, it is very unlikely, or it will never happen, we are discovering that it is more possible than was believed in the past, in the past it was believed that the distance between the stars is enormous and that is impossible and if it happens it will happen so many thousands of years in the future that it will not have any relevance because the solar system will no longer exist, the sun will have died and it is impossible.


This belief is changing, the stars are approaching, moving and sometimes passing very close, in fact, the one coming towards the solar system right now called Gliese 710 has a little less than half the mass of the Sun, which is already a respectable mass, if the Sun has 333,000 times the mass of the Earth, Gliese 710 would have about 140,000 times the mass of the Earth, this star is now about 63 years old light from us, but in a little less than 1,400,000 years it will be, according to the most optimistic forecasts, only one light year away and according to the pessimistic ones, it will be less than half a light year away.




The outer Oort cloud would be a year and a half light away, it would be entering directly into the Oort cloud, the cloud of comets and dwarf planets, the closest star currently to us is Proxima Centauri which is 4.2 light years away, this means that that star and everything it carries is going to get into the Oort cloud or in the most optimistic version it will brush past, but with everything it carries, when I say everything it carries it is because that star will obviously also have its small Oort cloud, it has less than half the mass of the sun, with its comets, its planets, dwarfs, etc. and all of this is going to get into our Oort cloud.


It will alter the orbit of the planets, no, because it will pass very far away, the light distance of the planetary system is about 5 light hours, from the sun to Pluto, but from the Sun to the last comet that is orbiting the Sun there is almost a light year, it is much greater, but what that star is going to do when it gets inside the Oort cloud will be to alter the orbit of thousands of comets, perhaps some dwarf planet, and it will surely cause a shower of comets towards the planetary system because they will end up those comets altered and falling towards the sun and onto the planets.


I remind you that a comet bombardment was what caused us to have water on Earth, perhaps what caused this was the passage near the sun or the solar system of stars in the past, perhaps they would be the cause of those comet bombers that brought water to Earth, what happens is that it will also happen in the future within 1,400,000 years, you are warned.
